Abstract: This paper analyses basic reservoir formation conditions and its characteristics of deep gas in Du-Qiao-Bai area, points out the distribution characters of oil and gas reservoir of "oil in upper zone and gas in lower zone" in Qiaokou area and the character of "Pagoda-shape" for integrated oil and gas distribution in Baimiao area. All types of reservoir in the area are complex gas reservoir controlled by structure and lithology.On this basis and with the theory of abnormal pressure liquid, it analyses focally on the models of inside compartment and fringes compartment for deep gas in Du-Qiao-Bai area. The reservoir model in Du Zhai is inside compartment and fringes of the compartment in Qiaokou. The reservoir model in middle and lower gas pools in Baimiao area belongs to outside compartment. The paper further concludes the control factors of deep gas reservoir in Du-Qiao-Bai area that has great significance for deepening the understanding of oil and gas enrichment law and the determination of future exploration strategy.
